Microsoft released its final set of Patch Tuesday updates for 2023, closing out 34 flaws in its software, making it one of the lightest releases in recent years. Of the 34 shortcomings, four are rated Critical and 30 are rated Important in severity. The fixes are in addition to  18 flaws  Microsoft addressed in its Chromium-based Edge browser since the release of  Patch Tuesday updates for November 2023 . According to data from the  Zero Day Initiative , the software giant has patched more than 900 flaws this year, making it one of the busiest years for Microsoft patches. For comparison, Redmond resolved 917 CVEs in 2022. While none of the vulnerabilities are listed as publicly known or under active attack at the time of release, some of the notable ones are listed below - CVE-2023-35628  (CVSS score: 8.1) - Windows MSHTML Platform Remote Code Execution Vulnerability CVE-2023-35630  (CVSS score: 8.8) - Internet Connection Sharing (ICS) Remote Code Execution Vulnerability CVE-2

Researchers have demonstrated yet another variant of the SAD DNS cache poisoning attack that leaves about 38% of the domain name resolvers vulnerable, enabling attackers to redirect traffic originally destined to legitimate websites to a server under their control. "The  attack  allows an off-path attacker to inject a malicious DNS record into a DNS cache," University of California researchers Keyu Man, Xin'an Zhou, and Zhiyun Qian  said . "SAD DNS attack allows an attacker to redirect any traffic (originally destined to a specific domain) to his own server and then become a man-in-the-middle (MITM) attacker, allowing eavesdropping and tampering of the communication." The latest flaw affects Linux kernels as well as popular DNS software, including BIND, Unbound, and dnsmasq running on top of Linux, but not when run on other operating systems FreeBSD or Windows. From Kaminsky Attack to SAD DNS DNS cache poisoning, also called DNS spoofing, is a  technique  i

The introduction of Open AI's ChatGPT was a defining moment for the software industry, touching off a GenAI race with its November 2022 release. SaaS vendors are now rushing to upgrade tools with enhanced productivity capabilities that are driven by generative AI. Among a wide range of uses, GenAI tools make it easier for developers to build software, assist sales teams in mundane email writing, help marketers produce unique content at low cost, and enable teams and creatives to brainstorm new ideas.  Recent significant GenAI product launches include Microsoft 365 Copilot, GitHub Copilot, and Salesforce Einstein GPT. Notably, these GenAI tools from leading SaaS providers are paid enhancements, a clear sign that no SaaS provider will want to miss out on cashing in on the GenAI transformation. Google will soon launch its SGE "Search Generative Experience" platform for premium AI-generated summaries rather than a list of websites.  At this pace, it's just a matter of a short time befo

In 1982, when SMTP was first specified, it did not contain any mechanism for providing security at the transport level to secure communications between mail transfer agents. Later, in 1999, the STARTTLS command was added to SMTP that in turn supported the encryption of emails in between the servers, providing the ability to convert a non-secure connection into a secure one that is encrypted using TLS protocol. However, encryption is optional in SMTP, which implies that emails can be sent in plaintext.  Mail Transfer Agent-Strict Transport Security (MTA-STS)  is a relatively new standard that enables mail service providers the ability to enforce Transport Layer Security (TLS) to secure SMTP connections and to specify whether the sending SMTP servers should refuse to deliver emails to MX hosts that that does not offer TLS with a reliable server certificate. It has been proven to successfully mitigate TLS downgrade attacks and Man-in-the-Middle (MitM) attacks. SMTP TLS Reporting (TLS-

The popular DSL wireless router model from D-Link are allegedly vulnerable to a software bug that could allow remote hackers to modify the DNS (Domain Name System) settings on affected routers and to hijack users' traffic. The main goal of DNS hijacking is to secretly redirect user's traffic from a legitimate websites to a malicious one controlled by hackers. The vulnerability might also affects other devices because it is located in the same, widely-used wireless router firmware used by different manufacturers. Bulgarian security researcher Todor Donev discovered the flaw which exists in a widely deployed ZynOS firmware from ZyXEL Communications Corporation, that is used in network hardware from TP-Link Technologies, ZTE and D-Link. According to the security researcher, D-Link's popular DSL2740R wireless router and a number of other D-Link routers, particularly the DLS-320B, are vulnerable. Late last year, similar router vulnerability was discovered in the

After the Heartbleed bug that exposed half of the Internet vulnerable to hackers thereby marking as one of the largest Internet vulnerability in recent history, the critical flaw in the implementation of the DNS protocol could also represent a serious menace to the Internet security. A Serious security vulnerability has been discovered in the algorithms of DNS software – BIND by the two Israeli students ' Roee Hay ' and ' Jonathan Kalechstein ', who are working under a project out at the Laboratory of Computer Communication & Networking in the Faculty of Computer Science at the Technion , which was led by Dr. Gabi Nakibly from Rafael (Rafael Advanced Defense Systems Ltd.). Although, Technion students have not provided any detail explanation about the vulnerability , but indicated that by exploiting the DNS protocol flaw an attacker could redirect the users who are trying to visit a legitimate website to a fake and bogus website which the attacker con

PKNIC, The Pakistan domain registrar of .com.pk, .pk, org.pk and others domains has been reportedly hacked again yesterday. A hackers group named PakBugs has claimed that they have successfully penetrated PKNIC servers and gained control of around 23,000 domains which included some of the most popular pakistani media websites also. This is not the first time that PKNIC servers have been compromised. Earlier a Turkish hacker successfully managed to penetrate PKNIC servers and redirected 284 .pk domains. Hacker redirect / deface many websites by changing the DNS records (DNS spoofing) of the websites which are maintained by PKNIC. However, it took the hacker 5 hour to submit all his defacement's on zone-h to make mirror's.
